In my opinion, the MFSW is more important to have than front fog lights, unless you plan on using them as a night time decoration when your driving. If fogs are that important to you fit them later or get them in with the deal. In terms of colour and trim level, have good look round them, take the diesel and petrol variants out for a test drive, decide what one you like best and pick the colour that suits you. If your buying brand new, you're in the driving seat so to speak!
